Face Alignment using a 3D Deeply-initialized Ensemble of Regression Trees

1 code implementation5 Feb 2019 Roberto Valle, José M. Buenaposada, Antonio Valdés, Luis Baumela

In this paper we present 3DDE, a robust and efficient face alignment algorithm based on a coarse-to-fine cascade of ensembles of regression trees.

Geometrical analysis of polynomial lens distortion models

no code implementations10 Apr 2018 José I. Ronda, Antonio Valdés

These results allow to find generalizations of the most usually employed models while preserving the desired geometrical properties.

Autocalibration with the Minimum Number of Cameras with Known Pixel Shape

no code implementations5 Mar 2012 José I. Ronda, Antonio Valdés, Guillermo Gallego

In the absence of information about the internal camera parameters such as the focal length and the principal point, the knowledge of the camera pixel shape is usually the only available constraint.
